The upturning type support leg rotates upwards when being opened, the support leg 1 is rotatably arranged on the back of the main body 6 through a rotating connection mechanism, the supporting plate 5 is rotatably arranged at the lower end of the front of the main body 6 through the rotating connection mechanism, the support leg 1 is connected with the supporting plate 5 through the rotating connection mechanism, an intermittent connection structure is arranged in the rotating connection mechanism, the supporting plate 5 is synchronously driven to rotate and open through the rotating connection mechanism when the support leg 1 rotates backwards from the main body 6 to a first supporting angle (the first two partial diagrams in figure 4), the supporting plate 5 is synchronously driven to rotate and furl back to the main body through the rotating connection mechanism when the support leg 1 rotates forwards from the first supporting angle to the main body 6 (the 3 rd partial diagram in figure 4), and the intermittent connection structure enters an intermittent mode in the rotating process of the support leg 1 between the first supporting angle and a second supporting angle, the cutting leg 1 drives the pallet 5 (fig. 4, the latter part), and the pallet 5 is an upturned open type pallet, and is rotated upward when opened, and the pallet 5 is folded back to the main body 6 by being rotated downward (fig. 1, the state of fig. 1).

The first support angle may be set to a common minimum support angle (the opening angle of the leg 1 with respect to the body 6), such as an acute angle greater than 30 degrees, the pivoting opening angle of the platform is typically around 90 °, and the second support angle may be a common maximum support angle (the opening angle of the leg 1 with respect to the body 6), such as 160 °. After the supporting plate 5 and the supporting legs 1 are folded, the magnet can be completely adsorbed with the main body.

The supporting plate 5 is arranged at a position close to the lower part of the main body 6, a concave area 60 for the supporting plate 5 to be folded is arranged below the rotating axis of the supporting plate 5 of the main body 6, after the supporting plate 5 rotates upwards and is opened, the upturned supporting plate 5 forms a boundary between the upper body surface and the lower body surface of the supporting plate, and the appearance surface of the supporting plate is a bearing surface for placing a mobile phone. And the concave area is automatically filled after the supporting plate 5 is folded back to the main body 6, and the concave area 60 positioned below the concave area is not easy to cause residual sundries when not working, thereby being convenient for appearance beautification design and carrying.

The rotary connecting mechanism can adopt a connecting rod mechanism, a gear rack, a gear set mechanism or a combined structure of the structures. The rotating connection mechanism is internally provided with an accelerating matching structure, so that when the support leg 1 rotates backwards and is opened to a first supporting angle from a closed folding state, the supporting plate 5 is driven to rotate and is opened, and when the support leg 1 rotates forwards and is closed to a folding state from the first supporting angle, the supporting plate 5 is driven to rotate and fold back to the main body 6, the angular speed of the support leg 1 is smaller than that of the supporting plate 5 according to a certain proportion, and the speed ratio can be the ratio of the rotating angle when the supporting plate 5 is opened in place to the rotating angle when the support leg 1 is opened backwards to the first supporting angle. For example, the length of the second rod segment 20, described below, is greater than the length of the fourth rod segment 40, forming the accelerated fit configuration.

The main body is provided with a mounting bracket 7 of a rotary connecting mechanism, the mounting bracket 7 can be integrated, and the mounting bracket 7 can also be divided into an upper mounting bracket 71 and a lower mounting bracket 72 which are separated from each other near a connecting part of a support leg and a connecting part of a supporting plate as shown in embodiment 3.

Preferably, the rotary connecting mechanism can adopt a link mechanism, so that the thin design and the weight reduction are facilitated. The rotary connecting mechanism comprises a first section of rod 10, a second section of rod 20, a third section of rod, a fourth section of rod 40 and a fifth section of rod 50; and the intermittent connection structure is arranged therein, when the support leg 1 is opened backwards from the folded state to a first supporting angle, the intermittent connection structure is in a connection mode, the rotation of the support leg 1 can drive the supporting plate 5 to be lifted upwards and rotate in place, correspondingly, when the support leg 1 is rotated forwards from the first supporting angle to the folded state, the intermittent connection structure is also in the connection mode, and the rotation of the support leg 1 can drive the supporting plate 5 to rotate downwards to the folded state; when stabilizer blade 1 rotates first support angle, can realize conventional support needs, according to the difference of scene and individual hobby difference, can also further increase stabilizer blade 1's turned angle, and at this moment, intermittent type connection structure gets into intermittent type mode, and stabilizer blade 1 is in the rotation process between first support angle and second support angle, intermittent type connection structure cuts off the drive connection relation between first section pole 10 and fifth section pole 50 and prevents layer board 5 reverse rotation, and layer board 5 can not rotate down, and current layer board support angle is not influenced.

The supporting foot 1 is connected with the first section of rod 10, or the supporting foot 1 is the first section of rod 10 and is made into a whole. The supporting plate 5 is connected with the fifth section of rod 50, or the supporting plate 5 is the fifth section of rod 50 and is made into a whole.

The second-stage rod 20 is a rod between the virtual axis E and the shaft D, and the first-stage rod 10 and the second-stage rod 20 form a lever with the virtual axis E as a rotation fulcrum. The fourth-segment rod 40 is a rod between the virtual axis B and the connecting shaft C, and the fifth-segment rod 50 and the fourth-segment rod 40 form a lever with the virtual axis B as a rotation fulcrum.

The upper end (first end) of the third rod segment is rotatably connected to the second end of the second rod segment 20, and the lower end (second end) of the third rod segment is connected to the first end of the fourth rod segment 40 by the intermittent connection structure.

The connecting shaft D of the upper end of the third section of rod and the second end of the second section of rod is a movable shaft capable of moving.

The third rod is arranged substantially along the length of said body 6, in which direction the third rod is a long rod, the length of which is substantially close to the distance between the rotation axis of the foot (virtual axis E) and the rotation axis of the pallet (virtual axis B). The third rod segment can be divided into two rod segments, namely a first rod segment 31 at the upper part and a second rod segment 32 at the lower part, so that the assembly and control are more convenient. The mounting bracket 7 is provided therein with a guide hole or groove 70 as a linear motion guide hole of the rod 32 which is located at the lower side and moves linearly, the rod 32 is provided with a connecting shaft 32-1 and a guide pin 32-2 which are matched with the guide hole 70, and the connecting shaft 32-1 rotatably connects the first link rod 31 and the second link rod 32.

The intermittent coupling structure includes a forwardly open coupling groove 321 provided on the second link lever 32, an intermittent mode control surface 322 in front of the coupling groove, and a coupling shaft C provided at the first end of the fourth link lever. When the leg 1 rotates backward from the main body 6 to the first supporting angle, the second link lever 32 continues to move straight downward, the connecting shaft C is located in the connecting groove 321 and is connected and matched with the upper side groove wall C1 of the connecting groove 321 to generate a driving connection relationship, and also gradually rotates out of the groove during the process that the leg gradually rotates backward from the main body 6 to the first supporting angle (the second link lever 32 continues to move straight downward), when the leg 1 rotates to the first supporting angle, the connecting shaft rotates to the intermittent mode control surface 322 in front of the connecting groove, at this time, the supporting plate 5 is also driven to rotate upward and in place, such as an angle substantially perpendicular to the main body 6, if the rotating angle of the leg 1 is continuously increased, the intermittent mode is entered, at this time, when the second link lever 32 continuously moves straight downward, the intermittent mode control surface 322 is in plane to be matched with the cam surface of the connecting shaft C, so as to prevent the supporting plate 5 from rotating upward and downward, so that the supporting angle of the foot 1 can be freely adjusted between the first supporting angle and the second supporting angle. The second link lever 32 moving linearly can simplify the control design between the intermittent mode control surface 322 and the connecting shaft C.

When the supporting leg 1 is rotated back to the first supporting angle from a position larger than the first supporting angle, the second link 32 moves upward, and when the supporting leg 1 is rotated back to the folded state from the first supporting angle, the connecting shaft C enters the connecting groove 321 again, cooperates with the lower side groove wall C2 to generate the driving connection relationship, and maintains the driving connection relationship during the process that the supporting leg 1 is gradually rotated forward to be folded (the second link 32 moves linearly upward continuously).

The above intermittent coupling structure may also adopt an intermittent gear coupling structure or the cam control structure of embodiment 4, etc., but this solution can apply a virtual shaft structure, which can increase the elegance of the appearance.

The rotary connection structure can also be provided with a structure which can stop rotating at any time and can be positioned at any time, particularly in the rotary stroke of the support leg 1 between the first support angle and the second support angle, so that the support leg 1 can be randomly positioned when the support angle is adjusted. The structure can be arranged at the position of a shaft D, the first section rod 31 is connected with the shaft D through the reed pipe structure 311, and the random positioning function interval which can be stopped rotating at any time and positioned at any time can be adjusted by designing the interference position and the interference angle of the reed pipe structure 311 and the shaft D

The rotation axes of the support legs 1 and the supporting plate 5 are virtual axes (one of the rotation axes can be a virtual axis or both of the rotation axes can be a solid axis), and the axes of the rotation axes (the virtual axis E and the virtual axis B) are arranged outside or below the surface of the main body or on the surface of the main body, so that the joints of the support legs 1 and the supporting plate 5 and the main body 6 are thinned into a line when the support legs are opened, and the fineness of the appearance is improved. For this embodiment, the arc rails 81 and 82 of the support leg 1 and the supporting plate 5 are disposed on the mounting bracket 7, and the centers of the arc rails 81 and 82 are the virtual axis E and the virtual axis B, respectively.

The first section rod 10 is slidably connected with the circular arc guide rail 81 along the circular arc shape through a circular arc sliding block 91 concentric with the circular arc guide rail 81, and the fifth section rod 50 is slidably connected with the circular arc guide rail 82 through a circular arc sliding block 92 concentric with the circular arc guide rail 82. For the rotational connection of the second-stage rod and the third-stage rod, the shaft D is at the eccentric position of the arc slider 91 (the part of the arc slider 91 from the virtual axis E to the rotating shaft D is used as the second-stage rod); for the connection of the third-stage rod and the fourth-stage rod, the connecting shaft C is also at the eccentric position of the circular arc slider 92 (the part of the circular arc slider 92 from the virtual axis B to the connecting shaft C is used as the fourth-stage rod).

The arc slider 91 is slidably connected to the arc guide rail 81 along an arc by a corresponding concentric middle arc slider 911, and the arc slider 91 and the middle arc slider 911 are slidably connected along an arc.

In the driving connection relationship before the first supporting angle, the second end 341 of the second link 34 and the first end 351 of the third link have an abutting relationship, the second link 34 continuously moves linearly downward when the foot 1 rotates backward from the main body 6 to the first supporting angle, the third link 35 descends due to the aforementioned abutting driving relationship, and the guide pin 350 also continuously descends along the L-shaped guide groove 75 in the process that the foot 1 gradually rotates backward from the main body 6 to the first supporting angle (the second link 34 continuously moves linearly downward), and the guide pin 350 moves right to the corner of the L-shaped guide groove when the foot 1 rotates to the first supporting angle.

If the intermittent mode is entered by continuously increasing the rotation angle of the leg 1, and the second link 34 continues to move linearly downward, the third link 35 is pushed to cause the guide pin 350 to enter the curved portion of the guide groove 75 and advance along the curved portion, and the third lever 35 is raised to be offset from the second end 341 of the second lever 34, the second lever 34 is inserted into the lower portion of the third lever 35, the guide pin 350 is prevented from moving back, thereby, the abutting relationship between the second link 34 and the third link is released, the third link 35 is locked, the opening angle of the leg 1 is continuously increased, the second link 34 is continuously descended, the downward movement of the third link 35 is not driven, but the surface is slid, the rotation of the pallet 5 in the upward and downward directions is prevented, so that the supporting angle of the foot 1 can be freely adjusted between the first supporting angle and the second supporting angle. The linearly moving second link 34 can simplify the intermittent motion control between the second link 34 and the third link 35.

Likewise, a structure for stopping rotation at any time and positioning at any time can be arranged in the rotating connection structure, particularly in the rotating stroke of the support leg 1 between the first supporting angle and the second supporting angle, so that the support leg 1 can be randomly positioned when the supporting angle is adjusted.
